Judging by my e-mail, the Duchess of York is VERY popular. Before I added this FAQ section, I received more questions about her than about anyone else in royal history.

How can I donate to the charities Fergie founded? Scroll down on this page for a link to the Children in Crisis website. I can no longer find any information online about her (former?) U.S. charity, Chances for Children.

Where can I write to Fergie? You can try contacting her through her charities, or by sending her a letter care of her publisher (look inside one of her books for the publisher's address). Another option is to contact her or Prince Andrew care of Buckingham Palace, London SW1A 1AA, England.

The duchess also now has a Twitter account (scroll down to the Other Websites section for a link). I don't know whether she manages it herself or how often she reads and/or responds to tweets.

Who is Fergie's agent? I used to receive this question a lot, but I don't know the answer, sorry.

My Story by Sarah Ferguson and Jeff Coplon. In this surprising autobiography, the Duchess of York reveals herself as a deeply fearful and insecure woman who never thought she was good enough to be a member of the royal family. She accuses the "Grey Men" who work at Buckingham Palace of plotting to destroy her, but she mostly blames herself for the scandal surrounding her marriage, and has nothing but praise for Prince Andrew and the rest of the royal family. A very interesting book. Out of print, but available from Alibris.
